TYPOGRAPHICAL COIVIPOSING-IVIACI-IINE.

Application filed March 24, 1915.

To all whom it may concern:

Be it known that we, HERBERT PEARCE and JOHN ERNEST BILLiNe'roN, subjects of the King of the United Kingdom of Great Britain and vlreland, and residing at Linotype and Machinery Works, Broadheath, in the county of Chester, England, have invented new and useful Improvements in Typographical Composing-Machines, of which the following is a specification.

This invention relates to improvements in typographical composing machines particularly machines such as those known commercially under the trade mark Linotype, and kindred machines, and it has for its object to provide means for facilitating the detachment from the said machines, of what are known as the separator boxes.

The invention will be best understood by reference to the accompanying drawings in which v Figure 1 is a rear elevation of a separator box in working position on the machine of which latter only a small portion of an ad j acent part is represented; Fig. 2 is a view similar to Fig. 1 but partly in vertical section, showing the separator box in the act of being detached or removed from the machine, and Fig. 3 is an elevation as seen from the right-hand side of Fig. 1.

Heretofore diliiculty has been experienced in removing a separator box 1 from the distributing mechanism which receives the matrices leaving that box, for the reason that the separator cam 2 is rigidly attached to one of the distributer screws 3 and is of such a diameter that part of it projects into, and obstructs the path through which the front or back wall or both walls of the said separator box must pass in order to effect such a removal. According to the pres ent invention, this difficulty is entirely overcome by having the cam 2 rotatably attached to, and removable with, the separator box 1. For this purpose the cam 2 as shown best in Fig. 2, is formed in one part with, or is operatively fast to, a clutch member 4L, and together with that member is Specification of Letters Patent.

journaled in a bracket bearing 5 fast to one or other of the above-named front and back walls, and the said clutch member 4 is capable of being engaged with, and disengaged from, a counterpart clutch member 6 fast on the shaft 7 of particular distributor screw 3 from which it receives its rotary motion. In the construction illustrated, see particularly Fig. 2, the cam 2 and clutch member a are integral with each other and with an intermediate part or hollow shaft 8 which is that by which this whole entity is rotatably supported in the bracket bearing 5. This said entity is axially bored to substantially the diameter of the adjacent end of the distributer screw shaft 7, so that it can receive, and receive support from, that part of the said shaft. As an alternative to the before described clutch faces it may be explained that the detachable connection of the cam 2 to the distributor screw shaft 7 may be efiected by the engagement of a slot or recess in the right hand end of the hollow shaft 8, with a stud or projection fast to the said screw shaft.

The separator box 1 is held in operative position, that is to say, with the cam 2 in engagement with the distributer screw shaft 7, by any of the usual well-known means, and when these means are released, the box 1, together with the cam 2, can, as a single entity, be removed from the machine in a rightward direction as viewed in Fig. 2, a reversal of these operations being necessary to replace and secure the box in the machine.

Having described our invention, we declare that what we claim and desire to secure by Letters Patent is 1. In a typographical composing machine, the combination with a separator box removable from the machine, of a separator cam removable with it.

2. In a typographical composing machine, the combination with a separator box and a separator cam removable with it from the machine, of a clutch connecting the cam to its shaft and one member of which is removable with the said cam.

3. In a typographical composing machine,

the combination with a separator box removgral with the cam, the cam and clutch being able from the machine, of a separator cam bored out to fit on the shaft.

and a bearing for the cam, both removable In Witness whereof We have hereunto set With, and the latter 'fast to, the separator our hands in the presence of two Witnesses.
